Fluid And Electrolyte Shifts During Health Adult Marathon Runner

Research into the relationship between physiological variables and running performance has been variable. The aim of this study was to examine the relationship between 5k running performance and a number of physiological variables in a group of 11 trained club runners (Age 21.451.63yrs, Height 175.092.77cm, Weight 67.865.12kg). The athletes underwent a laboratory treadmill test to determine their maximum oxygen uptake (VO2 max) and running velocities at lactate threshold (v-Tlac) and blood lactate concentration of 4mM (v-OBLA). Running performance was determined by a 5k time-trial on an athletics

“Is it in you?’’ Gatorade Without Gatorade would it is safe to have long hour practices? Gatorade, the history, science, and technology that saved athletes from dehydration.

All throughout an athletes life they are told to drink plenty of water, and replace their fluids. Athletes are told this enough to the point where it makes numbs them since they heard it so many times to the point where they forget the extreme importance of proper hydration, proper hydration. Proper hydration is not only key to optimum health, but also to great performance. Athletes are told to drink plenty of water, but do they really know why? It is this writer’s opinion that a greater understanding of proper hydration can lead to better health and performance for athletes and help spread awareness for dehydration and over hydration.

This study targets the physical effect of caffeinated energy drinks on athletes, in both genders, in team sports, primarily the capacity of the participants to perform repeated sprints during a simulated match.

The best advise about replacing fluids during the less than one hour exercise is to:

It is important for anyone doing physical activity to keep well hydrated, for performance to be at its best. Sports drinks are specially formulated to help people rehydrate during or after exercise. Drinks such as Gatorade and Powerade contain the main electrolytes and carbohydrates, which are used by the working muscles, to maintain optimal sports performance (Medindia.net, 2014). The acidity of sports drinks and the sugars, is raising health concerns, and creates unnecessary calories. (Nutritionwonderland.com, 2014) Sports drinks are proven to only be necessary when working intensely for over 90 minutes, so an athlete running a marathon may need a Powerade, but water is the best source of hydration for exercise of 90min or less.

Staying hydrated when you are running is critical. It can be easy to become dehydrated when you're working yourself out and sweating up a storm, and this is even more of a problem when you like to run when it's hot outside. If you're carrying your water on you while you run, you'll be encouraged to take sips of water more often, which can help prevent dehydration. This can help you feel better while you are working out and can help prevent dizziness

Although the rule of thumb has always been to drink 64 ounces of fluid every day, runners often need more liquid. Drink a minimum of half of your body weight every day. A person who weighs 170 pounds should be drinking 85

After running, the body lose much electrolytes. It decreases nerve and muscle contraction. It cause you catch the ruler slower during measuring reaction time. Sport drink contains electrolytes such as calcium and potassium. Electrolytes are essential for nerve and muscle action. If the person drinks Gatorade after running, Gatorade will replace

Athletes must maintain proper hydration before, during, and after exercise. In most cases, plain water is all that is needed to refuel the body; however, serious athletes who exert themselves for over an hour need to consider replenishing their electrolytes (Science Buddies Staff 2). Even professionals agree that your body needs these electrolytes to stay energized and healthy (Miller et al.). The question is which drinks contain the most electrolytes needed to replenish your body during a demanding workout?

M1 give examples of the impact of energy balance and hydration in relation to sports performance

In an attempt to understand the underlying biological differences of these runners Pui W. Kong hypothesized that one variation is, “related to the fact that Kenyans generally live and train at high altitude (around 2000 m above sea level) influencing their oxygen capacity” (Kong, 2008). One study that addressed this compared Kenyan runners oxygen uptake, as well as blood ammonia

Exercise-associated hyponatremia (EAH) is the most reasonable explanation of adverse changes in athletes during the marathon events. Physiologically, EAH is defined as plasma- sodium concentration that is below 135mmol/L. According to the decreasing plasma sodium level and individual, there are diverse symptoms such as nausea, headache, lethargy and restlessness. Although the sodium in sports drink could postpone the beginning of hyponatremia, drinking too much could cause hyponatremia (Rosner and Kirven, 2007). That is, hyponatraemia is influenced by both dilution of body sodium in body water overload and depletion of body sodium in body water losses. A decreased plasma sodium concentration lead to an osmotic gradient between extracellular and intracellular fluid in brain cells, causing water transfer into cells and increasing intracellular volume (Rosner and Kirven, 2007). It triggers problem regarding tissue oedema, neurological and low blood sodium concentration.

Fluid includes water as well as drinks such as coffee, tea, fruit juices but also the food ingested. The average fluid intake provided from food is estimated to be around 20%.

The major reason anyone drinks fluid before, during and after physical activity is to replace the water that is lost through sweat. If the water isn't replaced dehydration will occur and performance will be hampered. The purpose of sports drinks is to help rehydrate your body quickly and help improve performance and productivity. This is accomplished through a well-balanced mix of water, sugar (carbohydrates) and salts (electrolytes), the major ingredients in most sports drinks. These ingredients, combined with a variety of fruit flavours, create pleasant tasting drinks that, according to the companies, are suppose to help your athletic performance. Results prove that commercial sport drinks generally accomplish what they set out to do.
